"Memory upgrade to Laptop?"

Hello, I am interested in upgrading the memory of my laptop. currently I have 512 DDR RAM, but when I go to my system properties it only says I have 384 MB. I would like to get 1GB more, but don't know what kind to get. I live in Canada, and these are two that I've found, anyone know why the price difference?

Nell first you need to know what kind of is in your laptop. This link goes to (cpu Z)which will give you a good idea of what kind pc2100 2700 3200 ect http://www.majorgeeks.com/download425.html
One reason memory appears low is it is shared with the Video (possiblity).
The upgrade is no biggy after that...
We need a little more information to help you out.

Please try 2 (two) 512 sticks instead of one (1)
gig stick; as this will AT LEAST give you a back up in case of one stick crashing!! You MUST SYNC the sticks to your FSB speed which is simple as after install; and going thru "installing new hardware protocols" click on "TOOLS" and select synchronize (SYNC).
